Answer:
142 degrees
Explanation:
We know that a parallelogram interior angles all have to add up to 360 degrees.
Opposite angles are congruent, and we know that 2 angles must be acute (and congruent) and 2 angles must be obtuse (and congruent).
This means that 2 angles also have to be supplementary.
In this case,
JKG and KGH have to be supplementary, meaning we can write an equation:
180=38+x
subtract 38 from both sides
142=x
So, KGH is 142 degrees.
Hope this helps! :)
